Despite reaching a deal with cornerback Dunta Robinson late Friday, the Chiefs apparently are still in the market for more secondary help, reaching out to Dolphins cornerback Sean Smith early Saturday.

According to Albert Breer of the NFL Network, the Chiefs “have shown an interest in CB Sean Smith early on in the contact period.”

Translated, they were on the phone a half hour ago, negotiating but not agreeing or anything.

Of course, long before the days of legal tampering, Smith was trying to cram the toothpaste back in the tube at the suggestion of old-fashioned tampering.

Adding Smith would legitimize a secondary that needs the help opposite Brandon Flowers.

Depending on the money in the Robinson deal, the Chiefs could easily justify using him as a nickel corner or even at safety if they landed Smith. Robinson’s a good tackler, and even if he’s not the same cover player he was, he adds value.

n a night the NFL sent a memo to teams saying that premature agreements with pending free agents will be frowned upon until Tuesday, the busy Chiefs kept things interesting by making some news.

ESPN’s Adam Schefter reported that the Chiefs have come to terms with Dunta Robinson on a three-year deal. Robinson, recently cut by the Falcons, was once considered a top cornerback. He never lived up to the huge contract the Falcons gave him, but he wasn’t terrible, either. He could thrive being the No. 2 cornerback in Kansas City. Robinson was free to agree to a deal because he was released and was not technically an unrestricted free agent.

There has been some early thought that Robinson, who turns 31 next month, can play nickel or even help at safety for the Chiefs. If that is the case, the Chiefs could still look at Alabama corner Dee Milliner with the No. 1 pick. A trio of Brandon Flowers, Robinson and Milliner would be stellar. Matt Williamson of Scouts Inc. likes the signing.

“He is pretty aggressive in all facets of playing the position -- which can be good and bad,” Williamson said of Robinson. “It can get him into trouble and he, in turn, can have some coverage lapses. Even though he never lived up to the contract he signed in Atlanta, I would still say he is a starting-caliber cornerback as a No. 2.”

Even as a starter, Robinson often plays the nickel spot in those situations.

And the Chiefs might not be out of the cornerback market. The NFL Network reports that the team has made contact with representatives of Miami’s Sean Smith. That move had been expected. Smith would start in Kansas City if signed, and the signing would give the Chiefs a powerhouse cornerback group.

The agreement with Robinson continues a busy stretch for the Chiefs, who have been by far the most active team in the NFL in the past 10 days. Along with Robinson, the Chiefs have agreed to trade for quarterback Alex Smith, signed standouts Dwayne Bowe and Dustin Colquitt to extensions, put the franchise tag on Branden Albert, reworked the contract of Tyson Jackson and cut tackle Eric Winston.

The Chiefs also have the top pick in April's draft. While Milliner could remain on the table depending on Robinson’s duties, the team might be leaning toward taking Texas A&M’s Luke Joeckel, with a plan for him to play right tackle for now, depending on Albert’s future.

Still, as the Robinson signing shows, the Chiefs can’t be expected to quiet down as they begin the Andy Reid era. Everything seems to be possible.
